Hi All
I used to think that if gas fields had not leaked their natural gas then
they should not leak CO2 but I can now see that this argument would be
changed by fracking.
However if the pressure is high enough the density of CO2 is higher than
that of sea water. If you fill a deep sea

But aren¹t deep ocean trenches generally subduction zones, so subject to
rather massive earthquakes, as recently occurred off Japan?

Hi Sam,
I agree with your analysis. It is a terrifying prospect with the East
Siberian Arctic Shelf (ESAS) in such a critical state [1] (see [2] from
2007 for background). We do have a real emergency. This is why I have
instigated a brainstorming workshop on September 3rd and 4th in
Michael writes in an earlier email that These are the same oil fields
that are being proposed for massive CO2 geological storage. Fracking
is rapidly taking that option off the table. I know a little about
CCS but not much about fracking - if this is a zero-sum game then
we've got a problem.
It's not that simple. This issue was covered at the royal society.
If reserves are deep enough, they will be kept stable by pressure. As long
as they're not perturbed and don't diffuse into anything, you should be ok.
If you're relying on pressure containment, then fracking is a problem.
I am not sure this made it to the list, so just to make sure.
